Heat pumps -- water to water

  1. Jul 6, 2015 #1
    Hello there,

    So with say a Ground Source Heat Pump you have a source of warm-ish water coming in at 10 - 15 degrees C or so, and using a Heat Pump you are able to get a central heating temperature of about 40 degrees for your central heating system.

    Could you in theory, use a inlet water temperature of say 30-35C and transfer the heat energy from this water into something useful like say a second loop of water around 50 - 60 degrees C.

    Basically I'm trying to cool water from 33C to 20C so it can be recycled in a cooling heat exchanger on a test rig.
    Recovering the heat is the most beneficial solution to this.

    Thank you for any help and advice

    Performance is specific to the design of the heat pump, so you should look at specific products to see what performance is available.
